I also have 100 invites to give out in case you run out.
If you don't know what gmail is.... well let me tell ya...
It's a free e-mail account that gives you 2678 MB of storage space. And it has some great features to go with it, like the desktop pop-up when you get mail. I use that option at work to see when I get mail.
i honestly have no clue. i forgot i had a gmail acct and decided to checked it out and it said i had 50 invites. its been almost a year since ive used it.
i used up 3, bro, friend, and myself ( from original 50 )
now i have 100 left
invites wont be necessary when its released to the public. they are still working on some aspects of the gmail service, like integration and shittzle like that. :dunno
